Rostock MAX v2 Assembly Guide – 4thEd.
5 – Preparing the Drive Motors
For this task, you'll need the following components:
The stepper motors that are shipped with your Rostock MAX v2 kit are equipped with a
“flatted' shaft. This means that a portion of the drive shaft has been ground flat. This ensures that a
properly tightened drive gear won't be able to rotate on the shaft when properly tightened.
Thread both of the grub screws into a drive gear
and then slide it on to the stepper shaft as shown. Make
sure that a grub screw is aligned with the flatted
portion of the shaft. You
also
want to make sure that the
end of the stepper shaft is flush with the outside face of
the drive gear – again, as shown below.
Get your thread locker
out and dribble a
tiny
bit
on the threads. Tighten the
grub screws with the
included Allen wrench.
Complete the gear installation on the other
two motors. Set aside when done.
